Abstract
The disclosure relates to a hydraulic accumulator, in particular in the form of a piston-type accumulator, having a separating element which is arranged in an accumulator housing and fluid-tightly separates two fluid chambers, in particular a closed accumulator chamber comprising a working gas and a liquid chamber comprising an operating liquid such as hydraulic oil, from one another, wherein a fluid port is fluidically connected to one of the fluid chambers. The hydraulic accumulator is characterised in that the fluid port has a magnetic-field-generating device which is received in a fixed position in the fluid port and separates magnetizable particles out of the fluid passing through the fluid port, to purify said fluid.
Claims20
A hydraulic accumulator, having a separating element which is arranged in an accumulator housing and separates two fluid chambers from one another in a fluid-tight manner, wherein a fluid port is fluidically connected to one of the fluid chambers, wherein the fluid port has a magnetic-field-generating device which is received in a fixed position in the fluid port and separates magnetisable particles out of the fluid passing through the fluid port so as to purify said fluid, and wherein
- the magnetic-field-generating device comprises a ring, which is received in an associated wall receptacle in the fluid port and held in position by a fixing sleeve.
A hydraulic accumulator, having a separating element which is arranged in an accumulator housing and separates two fluid chambers from one another in a fluid-tight manner, wherein a fluid port is fluidically connected to one of the fluid chambers, wherein the fluid port has a magnetic-field-generating device which is received in a fixed position in the fluid port and separates magnetisable particles out of the fluid passing through the fluid port so as to purify said fluid, and wherein the magnetic-field-generating device is a formed by a rod, which is part of a fixing plate with passages for fluid guidance and is inserted into the fluid port.
A hydraulic accumulator, having a separating element which is arranged in an accumulator housing and separates two fluid chambers from one another in a fluid-tight manner, wherein a fluid port is fluidically connected to one of the fluid chambers, wherein the fluid port has a magnetic-field-generating device which is received in a fixed position in the fluid port and separates magnetisable particles out of the fluid passing through the fluid port so as to purify said fluid, and wherein a free end of a rod, which is adjacent to and facing one fluid chamber of the accumulator housing, is in a concentric arrangement with a longitudinal axis of the accumulator housing flush with an upper side of an associated housing lid facing this fluid chamber.
A hydraulic accumulator, having a separating element which is arranged in an accumulator housing and separates two fluid chambers from one another in a fluid-tight manner, wherein a fluid port is fluidically connected to one of the fluid chambers, wherein the fluid port has a magnetic-field-generating device which is received in a fixed position in the fluid port and separates magnetisable particles out of the fluid passing through the fluid port so as to purify said fluid, and wherein the magnetic-field-generating device is a formed by a rod, which is part of a fixing plate with passages for fluid guidance and is screwed into the fluid port.
